Nope, but I have to say that little bit of extra core tightness is good when lifting on the edge of failure.
There is no magical force that weakens your core as soon as you wear a belt!I guess you can get away with you core weakening by using a belt.
People certainly can switch off their core, but used correctly you'll get as much activation with a belt as without.
Wearing a belt compensates for poor form. I used the wrong term... Belts aren't for me I'm afraid.
No. A belt helps to compensate for poor form and enables you I lift with poor form. I'm not saying that YOU do, but it Is one of the disadvantages of a belt. Obviously if you've got good form and a strong core you may be able to enhance your lifts and protect you on the limit - that's understandable and fine.
I do concede that if you've had lower back issues either through previous injury and so on, then yes using a belt is sensible.
**** just got realYou're core is made of blamange.
